I don't think you can really. Maybe there's a signature though.
you have to have the real one and see if its fake or not
The Ancient Mew card can be found real if the entire card is holographic, the attacks and new are in Japanese, and is from the first Pokemon Movie Event.
Pedigree cats are a result of many generations of breeding within the same breed. You cannot tell this by looking at a cat, only by recording the generations of cats. Technically a cat is not pedigree if you do not have a record of its family, even if it has been bred true, as you need proof of breed to enter it in a cat show as a pedigree.
Ask for a pedigree from the place you got it from.

When a dog has a pedigree it's bloodline can be traced back many generations in order to be able to tell if the animal has the quality of bloodline that it is claimed to have. It is like a family tree.

on any reprint it will have the year it was reprintedon the back of the card is small type on the side or bottom. If its laminated, dead givaway its a reprint.
you can tell if a yu gi oh card is fake if it is 1st edition and silver sticker in the bottem right hand corner but if it is gold sticker and first edition it is real and if you turn it other side and feel it if it is rough its fake if it is smooth it is real and if the words are a bit to fat it is most likely fake. ;)
* It is very poor etiquette to tell someone to get you a gift. Gifts are given from the heart or to celebrate a special event. Not everyone has a lot of money and if you get a card from the person then appreciate that.
